Warning: FileSystem.CopyFile operation failed. Could not find a part of the path

I tried to change the destiny path to the Computer Desktop but I get different warning, it is a directory, not a file, so I added the file name with extension after the desktop directory path but same warning than beggining. No idea what more to do or missing something.
